This is the reason why car locksmiths are needed! You might be able depending on the vehicle you own, to change your key yourself using software available on the internet. These pieces of software are not compatible with all models or makes and can be difficult to use. It is best to let a professional software your key because they have the correct tools and know exactly how to use it. To accomplish this, you'll need blank keys that are compatible with your vehicle's model and make. You can purchase keys online for a discount cost, but make sure they are blank.

The chips have to be programmed to work with your specific vehicle — making it impossible to just use any key fob that is compatible with your car even if it's duplicate. While this makes car theft more difficult however, it also means you cannot simply replace the broken key fob with a new one and expect the old one to remain working. This is why most people must contact an auto locksmith to program an entirely new key for their car, though it is possible to do it yourself in certain instances. You'll need two keys that work. Once you have them, sit in the driver's seat, and then access the ignition in your car. Insert your new key in the ignition, then turn it on to start your car.

The procedure may differ depending on the manufacturer, so read the instructions that came with your key, or search for your specific year/make/model online to find the exact steps. Consider purchasing a keyshell instead of a key head if you want to cut down on programming costs for key keys. The shell is the plastic piece with the key blade, therefore you can usually find them for less at hardware or auto parts stores. However, you'll need to transfer the internals from the previous key head (the circuit board and chip) into the new shell before it is programmed. This can be accomplished by a professional, however it will cost more than a standard spare key. A professional will require an advanced programer that could cost thousands of dollars to connect to your computer in your car. You may be able to purchase a less expensive version on the internet, but this option will not likely work with your vehicle.

This is done to protect against theft, and will require a professional locksmith be hired for each model. The key should be able to communicate with the computer onboard to unlock the doors and then start the engine. A professional auto locksmith will be able to figure this out quickly. Certain car brands are difficult to program even for a skilled professional. The process could take hours or days for these models. The procedure requires EEPROM programming that locksmiths do not have. Cars can also have a variety of other features that require a particular programming to operate effectively. This could be a remote start, automatic transmission or power windows. A professional auto locksmith will assist you if keys are lost or broken.
